Abstract
A shell form ballast has rounded corners for positioning inside a ballast housing for use with a fluorescent light bulb adapter. The ballast has rounded outer corners to meet both long-term life and power requirements, and spatial design constraints of a fluorescent lamp adapter assembly for use in an incandescent lighting fixture, and particularly for use in a recessed incandescent lighting fixture. The rounded outer corners of the ballast provide the ability for the shell form ballast to fit into a hollow housing for use in the recessed lighting fixture while simultaneously providing the shell form ballast a snug fit in the hollow housing, thereby minimizing gap growth.
